摘要
针对配电网中的新增负荷,分析了用户业扩负荷接入配电网后对电网的影响情况,提出一种基于改进的最小生成树算法优化负荷接入点的分析方法,对用户业扩负荷接入问题进行优化求解,并采用灵敏度分析方法对网架节点进行稳定性分析,验证了改进的最小生成树算法(prim)和灵敏度分析方法在配电网扩展规划中的可行性。通过与遗传算法(GA)相比较,得出采用prim算法规划的总费用较小且系统电压的静态稳定性较好。
In allusion to the new load in the distribution networks,analysis was made to the influencing condition of networks after the new users accessing to distribution networks.An analysis method based on improved prim to optimize load access point was presented to optimize solution of the problem of the new users accessing to distribution networks and to use the method of sensitivity analysis to analyze the stability,which validates that the method of the improved prim and the sensitivity analysis used in the expanded plan of distribution networks is feasible.Compared with the genetic algorithm（GA）,the expense of the improved prim is smaller and the stability in static state of the system voltage is better.
